Docs parser fails

[PicoCentauri]

Running mdacli with current development version of MDAnalysis the parse_docs is able to parse the docs. I pinned down the problematic entry to the universe attribute of DistanceMatrix in the diffusionmap.py. It can be easily seen by adding a print

print(klass, par_name, others_)

statement to before line L288

Most likely our regex is not able to parse the `... @joaomcteixeira do you have an idea?

Additionally it seems that MDAnalysis also got docstring entries using : and : to seperate the name and the type. I think we are not able to parse them...
